Vitamin E

Vitamin E has demonstrated significant benefits for period pain (dysmenorrhea) in several clinical trials. A well-designed study showed that 500 IU of vitamin E daily, started 2 days before menstruation and continued through the first 3 days of the period, significantly reduced both pain severity and duration compared to placebo. Vitamin E works by inhibiting prostaglandin synthesis and arachidonic acid release — the same mechanism as NSAIDs, but without the gastrointestinal side effects.

Women with painful periods who prefer a natural alternative or complement to pain medications like ibuprofen.

400–500 IU vitamin E daily, starting 2 days before your expected period and continuing through day 3 of menstruation. Mixed tocopherols are preferable to dl-alpha tocopherol.

Effects are typically seen in the first cycle of use when taken at the right time.

Very safe at recommended doses. Vitamin E is fat-soluble — avoid long-term high doses (above 1,000 IU daily).

May have mild blood-thinning effects — use caution with blood thinners. Choose natural vitamin E (d-alpha tocopherol) over synthetic (dl-alpha tocopherol).
